5 mechanism for adjusting the matrix line length and the slug ejectingmechanism.

Hitherto, when it has been desired to change the length of the line, ithas been necessary to carry out an adjustment at four different placeson the machine, namely, on the assembler slide, the matrix line deliverycarriage, the matrix line stop on the first elevator head and themovable vise jaw. In consequence of errors arising in one or more ofthese adjustments trouble has frequently occurred, since, if too much orinsufiicient space is left in the matrix line, the matrices becomejammed or tilted, thereby causing the machine to be stopped.

Again, a wrong adjustment may permit metal 6 to penetrate into theintervening spaces between the matrices or even prevent the matricesfrom being fully introduced into the line thereby again bringing themachine to a standstill.

It is one of the principal objects of the invention to eliminate theabove disadvantages and with this and other ends in view the inventionconsists in the provision of common operating means to adjust the lengthof the matrix line on the assembler slide and in the vise jaws and tocontrol the slug ejecting mechanism. In addition, means operated fromthe machine may be provided to return the matrix line stop on the firstelevator and the long finger on the delivery carriage to their originalpositions after move- 35 ment of the line therefrom.

To carry out the said adjustment, a guiderod associated with the movablevise jaw may be extended the length of the said jaw and of the assemblerslide and may be movable in the same direction as the said slide. Thesaid rod may be provided with a fixed stop which is adapted to engage acounter-abutment of the assembler slide. In order to compensate themovement of the vise, it is preferable to divide the guide rod 45 by acoupling which is transversely releasable but quite rigid in thedirection of adjustment, so

that one portion of the guide rod can partake in the movement when thevise frame is tilted downwardly, while the other portion remains infixed i0 guides on the machine.

The regulating lever for the slug ejecting mechanism may be adjustedthrough the adjustable mechanism common to the assembler slide and tothe vise jaw by means such as a lifting cam,

55 thereby achieving a further simplification of the controls; For thispurpose a rotatable adjusting handle element may be connected to theassembler slide and, to the vise jaw and this element may be providedwith a lifting cam engaging with the rod of the slug ejector regulatinglever. Ad- 5' vantageously, the lifting cam is divided into steps toenable adjustments of the slug ejector regu-- lating lever to be made topredetermined amounts. Further, the said ejector regulating lever isconveniently joined to its rod by meanslO of a-coupling which is soarranged that an inde-.-: pendent adjustment of the slug ejectingmechanism may be secured. This is an important matter in those caseswhere the length of the actualslug cast is such as to require an ejectormeasurement which is larger than the length of the line characters.

In order that the invention may be more clearly understood one formwhich it may assume will now be described withreference to theaccompanying drawings in which:

Figure 1 is a'side view of a portion of a typographical composingmachine showing the assembler slide and vise jaws and the upper portionof the first elevator, the intermediate channel, the matrix deliverycarriage'and the connection to the .slug ejecting mechanism, and thecommon adjusting mechanism;

Figure 8 is a longitudinal section on the line G--I-I of Figure 6.

Referring to the drawings:

I l is the assembler slide with the assembler finger 2. The assembler isdesignated with 3. On the assembler is located a small block 4 having areleasing pin 5, which, through the operation of a two-arm lever Bactuates the releasing pawl I, when the assembler ascends, whereby thelong finger 8, on the left-hand side of the matrix delivery carriage isreleased so as to allow the same to strike against the line of matriceswhich is now raised further upwards between the long finger 8 and theshort finger 9 of the right matrix delivery carriage. As is alreadyknown, the release of the short finger takes place when the assemblerreaches its uppermost position, so as to allow the matrix line to slidetowards the left through the intermediate channel In, until it reachesthe first elevator head H. In the first elevator head I the matrix linecomes up against the displaceable matrix line stop l2 and moves thelatter along in front. of it. The. matrix line stop is formed in knownmanner as a longitudinally displaceable bail, which is held in itstemporary position of adjustment. by a brake mechanism, not illustratedin the drawings. When the first elevator ascends into the distributingposition, the matrix line stop I 2 is engaged by the longitudinallymovable pusher I3 and is returned thereby into its initial position bythe operation of the link l4 and the lever |5 which issecured to a rockshaft 2| controlled from the cam shaft of the machine. The matrixdelivery carriage is returned by means of the link l6 which is attachedthereto and to the lever ll. The said lever is fixed toa rock shaft I8.The movement of the carriage to the left is brought about by means ofthe spring l9 bearing on the lever 20 and secured to the rock shaft l8.The return movement through the link I6 and lever I1 is controlled bymeans of a cam (not shown) engaging roller 22 on the arm 23 secured tothe shaft l8;

The lefthand vise jaw 24 of the vise frame is adjustable to the linelengths required as is usual in machines of the kind underconsideration. A guide rod 25 extends from the adjusting mechanism forthe jaw 24. The said guide rod 25 is subdivided into two parts which arejoined by means of a cross pin 26 which at one end is secured to theleft hand part of the rod 25 and at the other end engages in an aperturein the right hand part thereof. The result of this is to ensure acoupling which is releasable in the transverse direction, but rigid inthe direction of adjustment which makes it possible for the left-handportion of the guide rod to partake in the movement when the vise-frameis tilted downwardly, whereas the right-hand portion remains in itsguideways. To facilitate its engagement, the coupling pin 26 is pointedat its free end.

Upon the rod 25 is mounted a stationary stop 21 against which acounterabutment 28 of the assembler slide is adapted to engage. Thecounterabutment 28 is provided with a finely adjustable screw 29 and islocated on a lever 30 rigidly connected to the assembler slide and whichextends forward within the reach of the guide rod 25. A downwardlyrockable detent 3| is located onthe stop 21, which detent, after beingrocked downwardly, causes the counterabutment 28 to perform a smallsupplemental movement thereby allowing, as usual, the introduction of alast matrix. One end of the rod 25'is provided with scale divisions,which are employed for adjustment of the desired line length.

The common adjustment of the assembler I and of the vise jaw 24 iscarried out by actuation of an adjustable handle 32 which is rigidlyconnected to a shaft 33 which, in turn, is located in a holder 34 ofU-shaped cross section. The holder 34 is secured to the front part ofthe machine close to the assembler. A pinion 35 is mounted at one end ofthe shaft 33 which is in mesh with a rack bar 36 and the bar, in turn,is connected at 26 to the guide rod 25, and enables the commonadjustment of the assembler slide and the vise jaw 24 to be effected.

The regulating lever for the slug ejecting mechanism bears the referencenumber 31. It is linked to, a lever 38 through a substantiallyvertically extending rod 39 the said lever 38 being pivotally mounted inthe U-shaped holder 34. The lever 38, through a toothed stop 40, restsupon a lifting cam 4| rigidly connected to the shaft 33. The lever 38,near one end, rests upon a detent-like lever 42 which is located on theholder 34,. and mounted transversely to the shaft 33, and at the otherend bears against a sleeve 43 fast to the shaft 33.

The adjusting handle 32 with the shaft 33 is displaceable axially, andwhen the shaft is pulled out, the sleeve 43 causes the detent-like lever42 to perform an upward swinging movement whereby the lever 38' is movedinto its uppermost position,, from which it again drops down upon thevlifting cam 4|, when the adjusting handle 32, with the shaft 33v arepushed back. According to the adjustment of the lifting cam, itsperipheral distance from the axis of the shaft 33 varies so that thelever 38, the rod 39, and the regulating lever 3! are located atdifferent levels in accordance with the adjustment of the assemblerslide- I and of the vise jaw 24.

The lifting cam 4| is circumferentially divided into steps in accordancewith divisions on the regulating lever 31, which, generally, are of 2ems in width. In order to set the adjusting handle 32, a setting disc 44is used, which is integral with the hand grip 32, and is provided withcircumferential teeth corresponding in pitch to the scale divisions onthe assembler, for example /2 em. When the adjusting handle is pushedback, a blade-like stop 45 provided near the top part of the holder 34,engages the appropriate teeth of the adjusting disc 44, and therebyensures the maintenance of the selected position. Through the stepwiseconstruction of the lifting cam 4|, an unhindered adjustment of theassembler slide and vise jaw in em sizes within a 2 em limit ofadjustment of the slug ejecting mechanism can be made.

The regulating lever 31 is loosely connected to the adjusting mechanismbya rod coupling. For this purpose a lateral projection 46 is providedon the upper'partof the lever 31, the said projection extending from ahousing surrounding the rod 39, in which housing a coupling pin 4!resiliently engages a circumferential groove 48 in the guide rod 39. Thecoupling pin 4'! is secured to an angle lever 49 which is pivotallymounted on the projection 46, the said lever being displaceable by acam-like lever 50, so that under theinfiuence of the lever 50 thecoupling pin 41 can be pulled out of the groove 48, against the actionof a spring, and the connection between the regulating lever 31 and therod 39 thus released. The cam-like lever 50 is so arranged that it iscapable of being rocked together with the locking lever 5| which looksthe regulating lever 31. The lever 5| is usually held in the inactiveposition by means of a bolt 52. After the release of the bolt 52, thelocking lever 5| may be swung out of the way by a spring 53 and the camlever 5|] partaking in the said movement, the coupling pin 41 iswithdrawn, so as to effect the release of the regulating lever 31 fromthe rod 39. The lever 31 is then freely adjustable and a locking hook 54on the lever amen 5| which is adapted to engage a groove in a' serrateddisc 55 is used to determine the adjustment which may now be freelycarried out. If it is intended again to connect the lever 31' to the rod39, the locking leve'r 5| is tightened and bolted. The hook 54 is thenreleased from the serrated disc 55 so as to allow the lever 3'! a freemovement longitudinally of the rod 39 until the pin 41 drops again intothe groove 48.

The invention is not restricted to the constructional form illustrated,inasmuch as alterations in detail may be carried out without goingbeyond the scope of the invention, for instance, other preferred knownmeans of adjustment may be selected; the adjusting mechanism may also bemounted on a different part of the machine. Further, the vise jaw andthe assembler slide may also be connected by separate means to a commonadjusting mechanism, in which case these separate means may each containa special fine adjusting mechanism.
